CAR-AXLE LUBRICA I'OR.

SPECIFICATION forming part of Letters Patent No. 416,535, dated December 3, 1889.

Application filed March 29, 1889- $erial No. 305,271. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH WOOD, of Red Bank, in the county of Monmouth and State of New Jersey, have invented a new and Improved Car-Axle Lubricator, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and-improved lubricator specially designed for railroad-car axles, and which is simple and durable in construction, Very effective in operation, and supplies the axle with pure oil at all times, thus preventing overheating.

The invention consists of an oil-receptacle held in the car-axle box and provided with a curved top, and a wick resting on the said curved top and extending at its ends into the said receptacle.

The invention also consists in certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of thisspecification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied on a car-axle. Fig. 2 is a transverse section of the same on the line w x of Fig. 1. Fig. 3 is a sectional side elevation of the improvement on the line y y of Fig. 2, also showing the car-axle box, and Fig. at is a plan View of the oil-receptacle.

The journal A, the axle-brass B, and the axle-box O are of any approved construction, and in the latter is held an oil-receptacle D, containing oil or other lubricant, and provided with a top D, which is curved to the shape of the journal A, as is plainly shown in the drawings. Between the top D and the sides D of the oil-receptacle D are formed longitudinal openings D as illustrated in Fig. 4.

On the outside of the curved top D is held a wick H, passing at its ends through the longitudinal openings D into the oil contained in the receptacle D. On the under side of the oil-receptacle D are held a number of hooks E, extending beyond the sides and connected with springs F, extending upward and secured at their upper ends on hooks G, secured to the sides of the axle-brass B. The

springs F serve to hold the middle part of the wick H in contact with the journal A as the said wick is supported on the curved top D of the oil-receptacle D. The latter is supported by the springs F from theaxle-brass B, and the tension of the springs is regulated so as to' press the oil-receptacle D upward and hold the wick H against the journal A with such force that the wick is free to deliver oil or other lubricant to the journal without be ing itself exposed to much wear.

From the front of the oil-receptacle D extends a pipe I, bent up ward and serving for conveniently filling the oil-receptacle with the lubricant when the car-axle-box door is open.

It will be seen that the oil-receptacle D is suspended from the axle-brass by springs, and is not supported by the axle-box C. It will further be'seen that the lubricant contained in the oil-receptacle D passes by capillary attraction into the ends of the wick H and to the middle part of the same held in contact with the journal A, so that pure oil is always supplied to the journal, thus preventing any overheating of the same. It will further be seen that the oil-receptacle D, with its wick, can be easily and quickly detached at any time from the journal by unhooking the springs F from the aX1e-brass B.

The ends of the wick I-I may be fastened together to make one continuous band, so that in case the wick moves by the turning of the journal the wick will always be in contact with the journal and extend at all times into the lubricant contained in the receptacle D. The wick H may also be secured by staples or other means to the upper ends of the sides D of the receptacle D to prevent any movement of the wick. The apertures D in the receptacleD are of the same size as the wick H, so that dust and other impurities are prevented from passing into the oil-receptacle. The lubricant in the latter thus always keeps pure.

Having thus described my invention, whatI claim as new, and desireto secure by Letters Patent, is-

1. A car-axle lubricator comprising an oilreceptacle suspended from the axle-brass and provided with a fixed curved top, and a Wick resting on the said curved top and extending at its ends into the said receptacle, substantially as shown and described.

2. A car-axle lubricator comprising an oilreceptaele suspended from the axle-brass, and a wick held on top of the said oil-receptacle and in contact with the journal, the ends of the said wick extending into the oil contained in the said oil-receptacle, substantially as shown and described.

3. A car-axle lubricator comprising a receptacle containing the lubricant and yieldingly suspended from the car-axle brass, and a wick held on top of the said oil-receptacle and in contact with the axle-journal, the ends of the said wick extending into the lubricant contained in the said receptacle, substantially as shown and described.

4. A car-axle lubricator comprising an oilreccptacle containing a lubricant and provided with a curved top, springs fol-suspending' said oil-receptacle from the axle-brass, and a wick held on the out-er surface of the said top, its ends extending into the said oilreceptacle, substantially as shown and described.

5. The combination, with a journal and an axle-brass, of an oil-receptacle yieldingly suspended from the car-axle brass and provided with a curved top, and a wick held on the outer surface 01' the said curved top and against the said journal, the ends of the said wick extending into the said oil-receptacle, substantially as shown and described.

(5. The con1bination,with a journal and an axle-brass, of an oil-receptacle yieldingly suspended from the car-axle brass and provided with a curved top, a wick held on the outer surface of the said curved top and against the said journal, the ends of the said wick extending into the said oil-receptacle, and a pipe leading into the said oil-receptacle for filling the same with a lubricant, substantially as shown and described.
